Abstract

Selon des modes de réalisation représentatifs, l'invention concerne un article pouvant comprendre une couche de base qui s'étend le long d'une première dimension et d'une seconde dimension, la seconde dimension étant orthogonale à la première dimension. L'article peut également comprendre des rubans réfléchissants disposés sur une surface supérieure de la couche de base, dans laquelle les rubans réfléchissants positionnés le long d'un plan commun s'étendant dans la seconde dimension ont des angles dièdres qui changent en fonction de la distance à travers le plan commun.
